PSO

qc-ldpc码编程，围长为6，列重为3，无4环(The algorithm divides rows into three equal groups. The rows are then connnected to form a distance graph which is then transformed in to a matrix. Girth of six is maintained by avoiding four-cycles. No two rows are connected more than once (the row-column constraint).)

很快的求出各点对之间的最短距离，并且记录路径。(Quickly find out the point to the shortest distance between, and record path.)

说明：  齿轮传动simulink仿真内含行星齿轮传动在一定负载下的仿真模型(You can model the effects of heat flow and temperature change through an optional thermal conserving port. By default, the thermal port is hidden. To expose the thermal port, right-click the block in your model and, from the context menu, select Simscape > Block choices. Select a variant that includes a thermal port. Specify the associated thermal parameters for the component.)

Beginning a source photograph, this demo will create an image with a hand-painted appearance. It can do this in three distinct styles, Impressionist , Expressionist and Pointillist .

该代码描绘了服从正态阴影模型的路径损耗和自由空间的路径损耗。并且添加了阴影产生的随机效应。(The code depicts shading model subject to normal free-space path loss and the path loss. And add a shadow generated random effects.)

MVDR与改进的MVDR方法数字波束形成比较(the comparisom of the method of MVDR and its improved method MMVDR to realeze beamforming)

风力发电系统仿真，变速恒频，svpwm。(Wind power generation system simulation, variable speed constant frequency, SVPWM.)

matlab编写的kmeans聚类算法，最后输出每类聚类结果，可自行制定分类数，(kmeans clustering algorithm matlab prepared, the final output of each type of clustering result, the number of self-classification could be developed)

matlab的m文件 计算两幅影像的协方差 源码简洁高效(matlab m-file， computing the covariance of two images， simple and efficient source)

说明：  Simulation for comparison of DVR and Other compensating devices
